This study examines the impact of emotional intelligence on operational effectiveness, focusing on three key components: self-regulation, distress tolerance, and others' emotion appraisal. In today’s business environment, organizations need employees who can manage their own emotions and understand those of others to face challenges and maintain high levels of productivity. However, there is a gap in the literature regarding how these emotional competencies influence organizational performance. The research uses structural equation modeling (SEM) to analyze data collected from professionals across various industries in Colombia. The findings reveal that self-regulation enhances distress tolerance, which positively impacts operational effectiveness. Additionally, the ability to appraise others' emotions fosters collaboration and optimizes organizational outcomes. These results highlight the importance of developing emotional competencies as part of business strategies to improve overall performance. This study contributes to both academia and industry by providing a foundation for future research and practical recommendations for business leaders. It suggests that organizations invest in emotional development programs to cultivate a collaborative and resilient work environment, thereby maximizing operational effectiveness in complex and dynamic contexts.
